Modellierung von offenen Absorptionsanlagen zur Raum- und Prozessluftentfeuchtung
(2023)
Luftentfeuchtung erfolgt in herkömmlichen Trocknungs- und Klimatisierungsanlagen durch eine Kühlung der feuchten Luft unter ihren Taupunkt (Kondensationsentfeuchter) und einer anschließenden Erwärmung bis zu der gewünschten Temperatur. Das Prinzip dieser Betriebsweise birgt einen unnötigen Stromverbrauch. In der vorliegenden Dissertation wird daher ein alternatives Luftentfeuchtungsverfahren beschrieben, bei dem die Luftentfeuchtung durch einen offenen Absorptionsprozess realisiert wird. In dem offenen Absorptionsprozess ...

Finite element method for the accurate solution of diatomic molecules
(1989)
We present the Finite-Element-Method (FEM) in its application to quantum mechanical problems solving for diatomic molecules. Results for Hartree-Fock calculations of H_2 and Hartree-Fock-Slater calculations of molecules like N_2 and C0 have been obtained. The accuracy achieved with less then 5000 grid points for the total energies of these systems is 10_-8 a.u., which is demonstrated for N_2.

Beitrag zur Analyse sicherer Kommunikationsprotokolle im industriellen Einsatz
(2012-09-26)
Bei der Arbeit an sicherheitsgerichteten Kommunikationsprotokollen stellten sich immer wieder die Fragen nach der Eignung von einzelnen Mechanismen der Protokolle, um den Gefährdungen entsprechende Maßnahmen zur Beherrschung entgegenzusetzen.
Dabei waren durchweg die Anforderungen der IEC 61508 mit dem Safety Integrity Level 3 zu erfüllen. Die IEC 61508-2 ist mit 5 Zeilen Umfang für die wesentlichen Anforderungen an die sicherheitsgerichtete Kommunikation sehr kurz gehalten und die IEC 61784-3 war zu Beginn der ...

Pursuing a Developmental State Trade Agenda in a Neo-Liberal Context
(Rainer Hampp Verlag, München, Mering, 2014)
This book explains why it was possible for the Worker’s Party (PT) in Brazil and the African National Congress (ANC) in South Africa to pursue a developmental state trade policy, in spite of neoliberal constraints. The major theoretical lenses are three-fold. It applies state theory (macrolevel), policy network analysis (meso-level) and theories on political parties with emphasis on factional politics (micro-level). This book highlights the socio-political relevance of comparatively progressive policy frameworks and ...

Impact of ownership concentration and corporate governance on sustainability and stakeholder risk: An empirical Analysis of listed firms from USA, UK and Germany.
(Corporate ownership and control, 2017-03-05)
This thesis contributes to and extends the literature by observing the impact of corporate governance and different attributes of board effectiveness and firm level corporate governance mechanism on stakeholder risk. Like shareholders, stakeholders also face the agency problem and fear losing their hidden resources and efforts. This thesis defines this fear of losing resources and efforts and long-term sustainability prospects as stakeholder risk. Here, it is worthwhile to mention that this thesis also contributes ...

The interplay of sustainability and capital markets
(2023)
Humanity faces significant environmental and social challenges, e.g., climate change (UN, 2019). Those challenges are, to some extent, addressed by politics. For instance, the European Union (EU) tries to address environmental topics, such as climate change, with the EU Action Plan on Financing Sustainable Growth to steer capital flows into more sustainable business models (EU, 2018). This regulatory development, in conjunction with a surging demand for sustainable investment solutions leads to a pressing need for ...

Influence of the electronic shell structure on the elastic scattering of heavy ions
(1982)
The interatomic potential of the system I - I at intermediate and small distances is calculated from atomic DFS electron densities within a statistical model. Structures in the potential, due to the electronic shells, are investigated. Calculations of the elastic differential scattering cross section for small angles and several keV impact energies show a detailed peak pattern which can be correlated to individual electronic shell interaction.

Interatomic potential structures in highly ionized scattering systems
(1983)
The interatomic potential of the ion-atom scattering system I^N+-I at small intermediate internuclear distances is calculated for different charge states N from atomic Dirac-Focker-Slater (DFS) electron densities within a statistical model. The behaviour of the potential structures, due to ionized electronic shells, is studied by calculations of classical elastic differential scattering cross-sections.

Prediction of the azimuth angle dependence of the quasimolecular anisotropy in heavy ion collisions
(1979)
Within the quasimolecular (MO) kinematic dipole model we predict a strong dependence of the anisotropy of the MO radiation on the orientation of the heavy ion scattering plane relative to the direction of the photon detection plane.

Wissenschaftliche Begleitstudie. Sozialwirtschaft integriert "Neue Chancen in der Sozialwirtschaft - Qualifzierungsperspektive für Migrantinnen"
(2023-04)
Vor dem Hintergrund vielfacher gesellschaftspolitischer Entwicklungen zielt „Sozialwirtschaft integriert – Neue Chancen in der Sozialwirtschaft – Qualifizierungsperspektive für Migrantinnen“ (SoWi) als innovatives und zwischenzeitlich verstetigtes Projekt in der kommunalen Arbeitsförderung darauf ab, Teilhabemöglichkeiten am Arbeits- und Ausbildungsmarkt für Frauen zu eröffnen, die aufgrund ihres Migrationshintergrunds, ihrer sprachlichen Fähigkeiten sowie struktureller Barrieren mit unterschiedlichen Herausforderungen ...
